About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X400CA
The AirTAC MBLC63X400CA is a double-acting aluminum mini cylinder engineered for heavy-duty motion within a compact footprint. It generates 1558 N of push force and 1457 N of pull force at 0.5 MPa, making it well-suited for moving substantial masses across its 400 mm stroke. Unlike the base MBL series, this variant utilizes a screw-adjustable air cushion at both ends to smoothly decelerate the piston near the stroke limits, minimizing impact shock and vibration on high-energy moves.
This specific configuration includes a CA pivot back cover that swings on a pin to accommodate arcing or angular loads, which is particularly beneficial at this extended 400 mm length. The unit features a Ø16 mm carbon-steel rod with 20 µm hard-chrome plating and a heterogeneous two-way grease-retaining piston seal for lasting friction control. Because this SKU lacks the -S magnet suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X400CA Is Used
Injection Mold Extraction
Leveraging 1558 N of push force at 0.5 MPa, this cylinder safely pulls heavy plastic injection molds from tooling, using the tunable air cushion to prevent harsh snapping at the 400 mm stroke end.
Pallet Diverting
The CA pivot cover absorbs angular stress while diverting heavy loaded pallets along a conveyor line, allowing the 63 mm bore to drive the 400 mm stroke without binding the rod.
Automated Crate Stacking
Provides the necessary 318 kgf maximum theoretical thrust to lift filled cardboard crates, while the adjustable cushions slow the descent smoothly to protect the packaged goods.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X400CA the Right Cylinder?
When sizing this 63 mm bore (1558 N push at 0.5 MPa), you can step down to the 50 mm bore for 981 N of push force if the load is lighter and space is tighter, or step up to a larger ISO 15552 profile cylinder if you exceed the 318 kgf maximum theoretical capacity at 1.0 MPa. Choose this MBLC variant over the fixed rubber bumper of the standard MBL when your application cycles quickly or drives a heavy payload that would overwhelm a simple bumper.
At 400 mm of stroke, the Ø16 mm rod is highly susceptible to bending under side loads. The CA pivot back cover on this unit helps safely manage arcing forces, but for strictly linear loads without an external guide, consider the MBLD double-rod cylinder to prevent rod deflection. Remember that the adjustable air cushion only decelerates the piston near the end of travel; it is not a brake or load lock, so an external rod lock is required to hold position without live air pressure. Replacement parts must match the PT tapered port thread, G1/4 port size, M14x1.5 rod-end thread, and CA clevis back cover.

- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB / FA / SDB) and back cover (CA pivot / U flat-end).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X400CA FAQ
This 63 mm bore cylinder delivers a push force of 1558 N and a pull force of 1457 N at 0.5 MPa. At 0.7 MPa, the push force increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa.
The MBLC63X400CA features a screw-tunable pneumatic cushion at both ends. You adjust the needle to regulate exhaust flow near the stroke limits, decelerating the piston smoothly to protect the end covers on heavy or fast moves. It is strictly a deceleration device, not a load lock or brake.
